P0024 code definition

Camshaft Position B - Timing Over-Advanced or System Performance (Bank 2)

P0024代码的含义

P0024是OBD-II通用代码，表明发动机控制模块（ECM）已确定Bank 2排气凸轮轴的位置比ECM预期的要高。过度先进的位置可以是在凸轮轴时机的延迟或进步阶段。

What causes the P0024 code?

• 通过使用凸轮轴和曲轴传感器，ECM可检测到凸轮轴的时机过高。

• The Oil Control Valve (OCV) to the bank 2 camshaft is stuck closed or has clogged passages.

• The oil is too thick, causing the passages to become clogged due to lack of oil flow to or from the camshaft phasers that control the timing.

• The camshaft phaser is stuck in the advanced position due to damage or defects.

P0024代码的症状是什么？

• The Check Engine Light is turned on and the engine is put in failsafe mode.
• The engine may have a hard start condition.
• The engine may run rough, hesitate or stall depending how advanced the camshaft is.
• 该发动机可能在加速方面存在perimention问题。
• The engine's emissions may exceed federal levels and fail an emissions test.

注意：这些症状可能会根据凸轮轴时位置而改变。

机械师如何诊断P0024代码？

• 进行视觉检查以确定凸轮轴油控制阀的任何电连接器，接线或阀门2排气凸轮轴

• Checks that the engine is full of clean engine oil with the correct viscosity

• Scans and documents the codes received and views the freeze frame data to see when the code was set

• 重置并清除OBD-II故障代码，重新测试车辆以查看P0024代码是否返回

• 对P0024代码执行制造商的特定精确测试

注意：遵循制造商的建议精确测试，以缩小问题的范围，并有助于防止更换错误的组件。

诊断P0024代码时的常见错误

遵循以下简单指南以防止错误： *进行视觉检查以查看是否连接所有电气连接器。

• 检查发动机机油以查看它是否已满，干净并且对发动机具有正确的粘度。

• Test and verify the failure code comes back before any further tests are done.

• 制造商的精确测试程序应逐步遵循。

• Do not replace any sensors or components unless tests indicate a problem.

P0024代码有多严重？

• 发动机可能会不稳定，失速，犹豫，跑得粗糙或有困难的起始条件。

• 该发动机可能具有过多的燃油消耗，发动机组件的碳结垢以及各种驱动器投诉，具体取决于凸轮轴失败的位置。

• 发动机可能无法进行排放测试。

What repairs can fix the P0024 code?

• Clearing and retesting to verify the fault codes and performing a road test

• 更换油和过滤器to the proper oil viscosity per the engine's specifications

• 修理或更换接线到凸轮轴油控制阀2排气凸轮轴

• Replacing the camshaft OCV for bank 2 exhaust camshaft

Additional comments for consideration regarding the P0024 code

The code can be caused if the oil is sludged up and has restricted the oil passages through the camshaft to the camshaft phasers, causing the timing to be over advanced.
